3. The Indulgence of 1515.—The XCV Theses were called forth by the preaching of the "Jubilee Indulgence" [25] of 1510, which was not placed on sale in central Germany until 1515. The financial needs of the papacy were never greater than in the last years of the XV. and the first years of the XVI. Century, and they were further increased by the resolve of Julius II. to erect a new church of St. Peter, which should surpass in magnificence all the churches of the world. The indulgence of 1510 was an extraordinary financial measure, the proceeds of which were to pay for the erection of the new Basilica, but when Julius died in 1513, the church was not completed, and the money had not been raised. The double task was bequeathed to his successor, Leo X. On the 31st of March, 1515, Leo proclaimed a plenary indulgence for the Archbishops of Magdeburg and Mainz, and appointed Albrecht, of Brandenburg, who was the incumbent of both sees and of the bishopric of Halberstadt as well, Commissioner for the sale of this indulgence. By a secret agreement, of which Luther was, of course, entirely ignorant, one-half of the proceeds was to be paid to the Fuggers of Ausburg on account of money advanced to the Archbishop for the payment of the fees to Rome, and of the sums demanded in consideration of a dispensation allowing him to occupy three sees at the same time; the other half of the proceeds was to go to the papal treasury to be applied to the building of the new church. The period during which the indulgence was to be on sale was eight years.
